M. TUDOROV OIL BURNER Filed Feb. l5, 1929 1 Y L w m Nm Patented May 5, 1931 UNITED STATES PATENT. OFFICE MARK() TUDORQV, 0F SAN'` IEEDRO, CALIFORNIA om BURNn-n' Application mea February 15,1921; serial No. 1240,201.

Another object of the invention is to prof vide an oil burner of such a character as to collect substantially all of the carbon at one point where it may be instantly removed by means of the rubbing part of the burner member upon other parts thereof, or by the application of a rod through slots in the fireshield.

A further object of the invention is to provide an oil burner of such character as to allow the fuel oil used to produce the desired fire to also iiush and clean the burner after the carbon adhering thereto has been bro-ken loose. Y

A further object of the invention is to provide a knock-down crude oil burner of such character as toenable it to be quickly disassembled for the removal of broken parts, and to as quickly assemble it again when necessary.

Other objects of the invention will be apparent as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion'throughout the several figuresV of the drawings and of which there may be modiications.

The numeral 1 represents a portion of the lire dooror other opening of the fire box shield through which the burner is installed, and whichis secured thereto by means of the lflanged ring 2. 1 r H s The burner comprises an outer pipe 3 which passes through the langedannulus 2A land is secured in place thereinA by means of the set screw 4.v l The boss 5 is held onthe end of-the pipe 3 withinthe reboX by a suitable setscrew, The funnelshaped fire shield 6 is integral with the boss 5'and has its outer edge thickened as indicated at 7 to prevent it from The large ttngSisheld in positionron the rear`end fof the pipe 3 by means'of the -set screw9.v This fitting is provided with-aU threaded bushing 110 which is screwed thereinto and set-in a given position by means of the'locknut 11,1the 'oil pipe 12 also being threaded into said'bushing. This bushing 'has its end` inside ofthe fitting 8 coned` as p Vindicated at13-'topermit it tov make a tight joint with' the elbow 14 simply by the pressure upontheelbowof the screw ljwhich screw has the hand wheel 16 lfor turning it.

The elbowv y14 isconnectedtofaJ pipe'17 which Y extends through the pipe 3 andhas `a nozzle A18 at its vendjust at the narrowest portion of thel ireshield6. i ,1" y f Arod 19- extends through the elbow 14 and pipe 17 carrying acleaning pin 20 at'its end. As the oil is deliverednto theinsideiof the p elbow shaped `fitting 14it lis prevented i from escaping therefrom by means of a packing gland 22, and it passes through an opening in 5o Figure 6 is a transverse sectional view on which the spring )installedV around the {floo rod 19 into the space inside of lthe pipe 17. This spring 28 rests upon a square washer 24 which washer has a plurality of cuts 25 therein to permit the passage of the oil.

Another spring 26 surrounds the rod 19 and bears upon the opposite side of the washer 24 and upon the end of a short tubular member 27 which also bears on the slotted cleaning nozzle 28.

The slotted cleaning nozzle Q8 fits the insideof the nozzle 18 and has several grooves therein as indicated at 29 to allow the es cape of oil to Ithe hole in the nozzle 18.

The nozzle 28 is held. in alignment with the rod 19 and rotated therewith by means ,ofthe pin 80, which passes through the Lrod 19 and into the two slots-in 4the nozzle 28.

T hgpll 20 is in alignment with the hole in the nozzle 18, and is carried Vby the end 20 of the rod 19 so that by pushing forward on the rod -19 the pin 2O will be projected A through the hole in the nozzle 18, and whenever desired, the rod 19 may be turned to rotate the nozzle 28 thereby aiding in cleaning 4any carbon .that may form inside the burner nozzles.

In operation the handle 32 on the end of the Arod 19 is turned and said rod is reciprocated from time to time thereby insuring the cleaning of the inside of the burner pipe 17 at its nozzle end. The `fireman may also from time to time examine the condition of the fire by looking-through the two slots 33 inthe burner shield;6 and if'he finds that any considerable accumulation of carbon has taken place onthe end'of the nozzle 18 he can knock vit off by pushing a flat bar through either or both of said slots.

Having thus described my invention, what I 4desire to secure by Letters Patent of the United States is as follows, but modications .may be made in carrying out ,the invention as shown in the .drawings and in the above particularly described form thereof, withinthe purview of the annexed claim.

I claim: Y

An `oil burner comprising a fixed tubular body having a conical nozzle .with a central olce, ,a tubular member rotatable in said tubular body and having a conical end fitting .Within said tip and having a central opening registering with said orifice, a Vrod slidably mounted in said tubular member and splined Vthereto, a p in mounted in the end of said rod and passing through the opening in the conical `end of said tubular member, an operating handle on the end -of said rod 4for manually advancing said pin into saidorilice or rotating said tubular member, and means for tdelivering fuel koil to said orifice. l

In'testimony whereof I have hereunto `set my hand' this 6th' any er Febfugiryyit 'n 1929?"v 'Manno TUDOBQY.
